The double chamber is supported 9o ber 1, to which oilis supplied under pressure, by the tube 27, the outer tube of the chamadouble chamber above the oil-chamber, ber being` preferably made, asshown, of a 4o comprising an outer tube 2O and an inner or size to fitwithin the upper end of tube 27.

connecting-pipe 30 is made sufficiently strong and in its connection tothe tube 27 sufficiently rigid to permit the whole device to besupported from the gas-Fixture, in which case the oil-supply tube 35will be led'along the gas-pipe from a suitable tank containing oil underpressure.

If the device is to be used as a table light, it should be provided witha suitable base, and the may be supplied from any convenient fixture byaflexible tube, the oil being supplied from a tank on or beneath thetable.

The device, as shown, being secured to a gas-supply pipe and the gasturned on, the gas will pass through the pipe 31 into the space betweenthe outer tube 27 and tube l5 and up through the mixing-tube 21 to theburner. Air will enter through the passages 16 and the air-inlet 23 andmix with the gas. A portion ofthe mixed gas and air Will be deflected bythe obstruction 25 into the downtake-passage and when ignited will becaused to form a cone of flame by the draft of air 'from the passages 16within the base of the mixing-tube. The main portion ofthe mixed gas andair will pass through the obstruction 25 to the burner, Where it will beignited and will heat the mantle to incandescence. The gas passingthrough the cone of liame will be highly heated and will more readilymix with the air entering through the air-inlet and will heat the mantlemore satisfactorily than in the burners in which the gas is not thusheated. As soon as the cone of flame is formed the outlet-valve of theoil-chamber may be opened. rlhe oil discharged is vaporized in itspassage through the cone of iiame and mixing` with the air enteringthrough the airinlet 23 and with the gas will form very rich gas, bywhich the mantle Will be heated to a m uch more brilliant incandescencethan could be secured without the addition ot' oil-vapor. When thevaporization of the oil is once begun, the gas-supply may be cutoff andthe device run as a vapor-burner.

By closing the outlet-valve of the oil-chamloer and regulating thegas-supply a low light may be kept burning, as desired, it beingneeessary only when a stronger light is desired to turn on the gas foran instant and open the outlet-valve of the oil-chamber.

By thus combining in one device a gas and Vapor burner I provide a lightwhich can be regulated between wide limits from thelowest light possiblewith a gas incandescent light to the most powerful light possible from avapor-burner.

While my invention has been described as a light, it should beunderstood that it may be used for general heating purposes, the articleto be heated being placed above the burner in place of the mantle. Thegas produced in the mixing-tube may, if desired, be used in a gas-engineor for any purpose for which a gaseous compound of vapor and air, suchas is there formed, may be adapted.

By the use of my device a gas-supply of inferior quality may be enrichedby the addition of oil-vapor, so that a light of great brilliance may beproduced.
